STREET-RAI LWAY.

SPECIFICATION forming part of LettersIatent No. 464,616, dated December8, 1891. Application filed September 25, 1890. Serial No. 366,165. (Nomodel.)

To all whom it may concern:

Be it known that I, WHrrcoMB L. J UDSON, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Street-Railways;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to that class of street and other railways whereinthe propelling mechanism is carried on a motor-car and is actuated byair, gas, or liquid under pressure contained in a receiver on the car,which is recharged at suitable intervals along the line of travel.

My invention is especially designed for what may be called theair-storage system,wherein compressed air is used as a motive power, thereceivers being of comparatively small size and adapted to receivecharges atrfrequent intervals from an air-main extending along the lineof travel.

My invention is more particularly directed to the charging mechanism,and is applicable to either surface or elevated roads; and it has forits object to provide asimple construction for automatically effectingthe charge while the car is in motion. To this end the airmain is placedadjacent to the track and at charging-points is provided with atelescoping section. In the telescoping section and telescopingtherewith is mounted a valve charging nozzle. The projecting end of thisnozzle is supported by a trolley movable on a track adjacent to themain, which is provided with an inclined surface at its head for raisingthe nozzle outward into its charging position and an inclined surface atits foot extended into'a pocket to permit the nozzle to return to itsnormal position after the passage of the car. On the motor-car is placeda movable guide bar or projection,which,when set in its lowermostposition, is adapted to engage the trolley and by the forward motion ofthe car raise the same onto its track and guide the charging-nozzle intoregistration withthe receiving-nozzle carried by the car. To set thismovable guide-bar in its lowermost position, a pivoted lever is placedon the car, which is adapted to be engaged with a projection extendedfrom the road-bed. To return the guide to its normal position after thecharge is completed, an inclined cam-surface is located in the line ofits travel on the road-bed and engages the projection from the movableguide. The connection between the pivoted trip-lever and the guide ismade by a connecting-rod pivoted to the guide at one end and having itsfree end working through a hole in the shaft of the trip-lever. Aresistance-spring is placed between the shaft and the guide. In virtueof this construction the springs line of resistance will be shiftedabove or below the trip-lever shaft and will hold the guide in eitherposition in which it may be set. To return the trolley and thetelescoping section to their normal position, a traveler is placed upona track at the foot of the charging-section, which is connected by acable passing over suitable sheaves to the trolley. The projection onthe movable guide bar engages with this traveler after passing thecharging-section and carries it forward until the traveler drops down anincline at the foot of its track into a pocket, which permits it toclear the car. The forward movement of the traveler returns the trolley,and the forward movement of the trolley, when engaged with the next car,returnst he traveler into its normal position at the head of its track.The movable guide, the trip-lever on the car, and the traveler with itsconnection to the trolley are similar to the constructions shown inanother application for a similar purpose filed by me of even dateherewith under Serial No. 366,164. The radical differences in thisapplication lie in the telescoping section of the air-main and in thetelescoping charging-nozzle. Other minor differences will beparticularly pointed out in the claims.

I have shown the invention as applied to an elevated road.

In the drawings like letters refer to like parts throughout.

Figure 1 is a view, partly in side elevation and partly in section,showing a motor-car in position on a charging-station. Fig. 2 is avertical cross-section on the line X X of Fig.

1. Figs. 3 and 4 are detail views, in side and frontelevation,respectively,showing the movable guide-bar and trip-lever.

A are elevated rails, and B their supporting structure.

0 is a motor-car, shown as of locomotivelike form, provided with areceiver 0 in the position occupied by the ordinary boiler.

D is the receivingnozzle, having an enlarged or bell-shaped mouthprovided with a valve D and a downwardly-projecting bridge (Z.

E E is the movable guide-bar or nozzleguide, mounted in straps e, fixedto the cartrucks.

F is the trip-lever, and F its pivoted shaft, mounted in hearings on thetruck.

E is a cross-bar or rod rigidly connecting the two bars E, which make upthe movable guide. a

G is the connecting-rod, pivoted at one end to the cross-rod E andhaving its other or free end working through a transverse hole orguidefin the trip-lever shaft F.

G is the resistance-spring on the connecting-rod G between the cross-rodE and the shaft F. a

II 11 II are adjacent sections of the airn1ain,of which H and H arefixed sections and I'lis a movable section telescoping with the fixedsections, working through suitable stufiing-boxes h and h. Thetelescoping section H is open at both ends. It is therefore balanced andeasily moved.

K is a central enlargement on the telescoping sect-ion, constituting thenozzle-seat.

L is the chargingnozzle, having its lower end located in said seat andworking through a stufling-box Z in the seat K, and spaced aparttherefrom is located a short pipe K, telescoping into the lower end ofthe nozzle-section and provided with an upturned annular flange K at itslower end, in which moves the enlarged lower end Z of thenozzle-section. The space inclosed by the flange K constitutes avacuum-chamber, into which the nozzle-section is forced by theair-pressure on the enlarged head Z.

M is the trolley supporting the head of the charging-nozzle, providedwith anti-friction rollers N N, located on the same axles with itsbearing-wheels for co-operation with the nozzle-guide E, located on thecar.

P is the trolley-track, inclined at its head and foot, as shown at p p.

P is a guide-rail fixed to the foot of the trolley-track and overhangingthe inclined part 1) to insure the trolley passing into its pocket.

Q is the inclined cam-surface at thefoot of the trolley-track forengaging with the projection Q, attached to the movable guide on thecar.

R is the traveler, and R its track.

R is the cable connecting the traveler and the trolley overguide-sheaves '1' r 0'.

R' is the inclined section or pocket at the foot of the travelers track.The valve L in the mouth of the charging-nozzle is provided with anoutwardly-extended stem d for cooperation with the bridge (Z in themouth of the receiving-nozzle to open the valve L by the weight of thecar upon the registration of the nozzles.

S is a stationary projection fixed in the roadway at the head of thecharging-station for cooperation with the trip-lever F on the car to setthe nozzle-guide.

The operation is as follows: \Vhen the triplever F strikes theprojection S, the nozzleguide E E is thrown down to its lowermostposition and held there by the spring G on the connecting-rod G. On thefurther motion of the car the nozzle-guide engages the antifrictionrollers N N on thetrolley and carries the trolley forward on thetrolley-track. On passing up the incline p at the head of the track thecharging-nozzle L is drawn upward out of the seat K and guided by thebars E into registration with the receiving-nozzle, the weight of theearopening its valve. The charge is then made either while the car is inmotion, if the trolley-track and telescoping section be of suflicientlength, or while the car is stopped for the purpose. On passing to thefoot of the trolley-track the trolley falls into its pocket, clearingthe car, and the projection Q, engages the inclined cam Q, restoring themovable guide E to its uppermost or normal position, where it is held bythe spring G on the rod G. Upon the further motion of the car theprojection Q, engages with the traveler R until the same drops into itspocket, and this forward motion of the traveler restores the trolley andthe charging-nozzle to their normal position in contact with the fixedsection II of the air-main. As the chargingnozzle was drawn outward fromits seat K by the upward movement of. the trolley it produeeda vacuum inthe chamber inclosed by the flanges K and Z. \Vhen the trolley isreleased from the car and passes into its pocket, the air-pressure onthe top of the flange L immediately restores the nozzle to its normalposition. The vacuum-chamber in the seat K may be provided with a ventfitted with a check-valve, as shown at q.

That I claim, and desire to secure by Letters Patent, is as follows:

1. The combination, with an air-conduit having a movable sectiontelescoping with the adjacent fixed sections, of an air-nozzle connectedto said movable section.

2. The combination, with an air-conduit having a movable sectiontelescoping with ad j acent fixed sections, of a nozzle-section seatedon said movable section at right angles to its axis and telescopingtherewith.

The combination, with an air-pipe, of a nozzle telescopically seatedthereon and a vacuum chamber in said nozzle-seat extended by the outwardmovement of the nozzle,

whereby the nozzle may be returned by the air-pressure.

4. The combination, with the movable car having a receiving-nozzle, ofan air-main along the line of travel and a charging-nozzletelescopically seated on said main at right angles receiving-nozzle anda guide for the chargingnozzle, of the air-main adjacent to the carstravel, having a movable section telescoping with the adjacent fixedsections, the charging-nozzle telescopically seated on said movablesection, the trolley supporting the head of said nozzle and adapted tobe engaged by said guide, and a trolley-track for uniting the nozzlesunder the action of the car.

7. The combination, with the movable car having a receiving-nozzle, ofthe air-main adjacent to the line of travel, having a movable sectiontelescoping with adjacent fixed sections and carrying a charging nozzle,and

means for returning the movable section to its normal position after thecharge is made.

8. The combination, with the car having the receiving-nozzle, of theair-main ad acent to the cars travel, having the movable sectiontelescoping with the adjacent fixed sec tions, the charging-nozzlemounted on said movable section, the trolley supporting the head of thenozzle, the trolley-track, the traveler and its track, the cableconnecting the traveler and trolley over guide-sheaves, and projectionon the car for engaging the trolley and the traveler, substantially asand for the purpose set forth.

9. The combination, with a movable car and an air-main extending alongthe line of travel, of a receiving-nozzle on the car, a

charging-nozzle connected with the main, and

a telescoping section of pipe supporting one of said nozzles to permitthe charge to be made while the car is in motion.

In testimony whereof I affix my signature in presence of two Witnesses.
